Artificial intelligence decisions are often described as explainable when a system can produce reasons, feature contributions, counterfactuals, or other interpretive outputs. Such outputs, however, do not by themselves make an institutional decision answerable. This article develops a conceptual explainable AI governance framework that treats explainability as an organizational obligation connected to transparency duties, system documentation, evidence preservation, auditability, responsibility allocation, contestability, human review, and redress. The framework distinguishes technical explanation from the governance capacities required to identify who must justify a decision, what information must be recorded, how evidence can be examined, how affected stakeholders may challenge an outcome, and whether an organization can correct errors or remediate consequences. Transparency and documentation are organized around system, model, data, dataset, and decision records, together with data, model, and decision provenance. Auditability is connected to traceability, lifecycle records, risk documentation, monitoring, incident response, and clearly allocated organizational responsibility. Contestability is connected to decision justification, appeal and complaint pathways, competent and sufficiently independent human review, escalation, correction, recourse, and redress capacity. The framework also identifies governance gaps that arise when these functions are separated across the AI lifecycle, including documentation, evidence-trail, accountability, human-review, monitoring, and remediation gaps. Its principal contribution is an answerability-oriented governance architecture that links explanation to institutional evidence and response mechanisms while preserving explicit boundaries: transparency does not independently establish accountability, auditability does not prove responsibility, human involvement does not guarantee meaningful review, and a conceptual governance framework does not establish legal compliance, procedural fairness, ethical sufficiency, or deployment readiness.

Generative artificial intelligence can produce fluent, context-sensitive, and apparently authoritative responses even when relevant knowledge is incomplete, evidence is unavailable, or generated claims are false. This creates an epistemic safety problem concerning not only what a system produces, but also what it appears to know, how its claims are supported, how uncertainty is expressed, and when answering should be limited. This article develops a conceptual safety framework organized around four operational principles: ground, qualify, verify, and abstain. The framework treats hallucination as a multidimensional risk involving fabrication, factuality failure, groundedness failure, unsupported claims, false confidence, source and context errors, reasoning errors, citation errors, overgeneralization, confabulation, speculative output, and incomplete evidence. Grounding links material claims to relevant and sufficiently reliable evidence; qualification communicates uncertainty, assumptions, scope, and evidential limitations; verification examines claims, sources, citations, and inferential consistency; and abstention enables refusal, deferral, escalation, or constrained output when evidence or system competence is insufficient. Human review, meaningful oversight, decision boundaries, failure containment, incident monitoring, and lifecycle updating operate across these principles rather than functioning as final guarantees. The main contribution is an integrated generative AI safety framework that connects output-level hallucination control with source quality, knowledge verification, uncertainty communication, review quality, response limitation, and downstream risk containment. The framework is intended to structure domain-specific assessment and future research. It does not independently establish factual reliability, ethical sufficiency, legal compliance, operational safety, certification, or deployment readiness.
